Thick lower lip vermilion |
"Increased thickness of the lower lip, leading to a prominent appearance of the lower lip. The height of the vermilion of the lower lip in the midline is more than 2 SD above the mean. Alternatively, an apparently increased height of the vermilion of the lower lip in the frontal view (subjective)." [HPO:curators, PMID:19125428] |
Normal values for the height of the vermilion are available [Farkas, 1981] but measurements are not commonly used. Most clinicians determine this feature subjectively. The lower lip is typically thicker than the upper one. The height of the vermilion of the lower lip varies among ethnic groups, and the vermilion should be compared to a population of same ethnic background. When the vermilion is thick, it is more convex and more everted than usual on profile view, but that should be assessed separately. |

Epicanthus |
"A fold of skin starting above the medial aspect of the upper eyelid and arching downward to cover, pass in front of and lateral to the medial canthus." [HPO:probinson] |

Congenital diaphragmatic hernia |
"The presence of a hernia of the diaphragm present at birth." [HPO:probinson] |
Diaphragmatic hernia is the result of a developmental defect causing an abnormal opening in the diaphragm, through which abdominal organs (stomach, spleen, liver, and intestines) can protrude into the thoracic cavity. This usually causes respiratory distress in the newborn period. |

Global developmental delay |
"A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age." [DDD:hvfirth, HPO:sdoelken] |
Developmental retardation is any significant lag in development in the any or all of the physical, cognitive, behavioral, emotional, or social spheres. Note that the term intellectual disability (mental retardation) refers to not merely a delay in development but rather a permanent limitation. Note that the term 'psychomotor retardation' is also used in some contexts to refer to a slowing of thought and physical movements as a result of major depression or intoxication. |

Hypotonia |
"Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist." [HPO:probinson, PMID:21418198] |
Hypotonia can be caused by abnormalities of the central nervous system, any element of the motor unit (including the lower motoneuron), or both. Hypotonia is not a specific diagnosis, but can be observed in hundreds of genetic and other diseases. The first distinction to make when assessing a child with hypotonia is whether decreased muscle tone is a result of an abnormality of the central nervous system (CNS), peripheral neuromuscular system, or a combined abnormality involving both. Clinical findings suggestive of an abnormality of the CNS may include hyperreflexia, cognitive developmental delay, and seizures. In contrast, physical findings pointing towards a neuromuscular origin may include weakness, lack of antigravity movements, muscle atrophy, fasciculations, and/or diminished reflexes, most often in the context of normal cognitive function. The HPO term does not distinguish between these etiologies. Additional HPO terms should be used as required to describe associated features. |

Myelomeningocele |
"Protrusion of the meninges and portions of the spinal cord through a defect of the vertebral column." [HPO:probinson] |
Meningomyelocele can result if more than one or two vertebral bodies are affected by spina bifida. The meningomyelocele is usually covered by a thin, vulnerable membrane. Meningomyelocele is generally accompanied by neurological deficits. |

Cryptorchidism |
"Testis in inguinal canal. That is, absence of one or both testes from the scrotum owing to failure of the testis or testes to descend through the inguinal canal to the scrotum." [HPO:probinson, PMID:23650202] |
The gonad is mobile and can be retracted superiorly by the cremaster muscle reflex stimulated, for instance, by cold or touch. A retracted testis is not cryptorchidism. An abdominal testis cannot be distinguished by physical examination from an (Apparently) absent testis and requires radiological (or, rarely, surgical) procedures for assessment. |

Depressed nasal bridge |
"Posterior positioning of the nasal root in relation to the overall facial profile for age." [PMID:19152422] |
The adjective "depressed" here does not indicate an active process but a status. A depressed nasal bridge can occur irrespective of the width of the nasal bridge, and the width should be assessed independently. In infancy, the nasal bridge is relatively more posterior than in the older person. The term depressed nasal bridge should only be used when the bridge is more posterior than is typical for age and ethnic background. |

Prominent nasal bridge |
"Anterior positioning of the nasal root in comparison to the usual positioning for age." [PMID:19152422] |
A prominent nasal bridge can occur irrespective of the width of the nasal bridge, and the width should be assessed separately. The nasal bridge becomes more prominent with age. Although the nasal root may be anteriorly placed without increasing the space between the eyes, prominence of the nasal bridge may be accompanied by Telecanthus or ocular Hypertelorism. If such findings are present these should be coded separately. Deep-set eyes may lead to the impression of a prominent nasal bridge, but this finding should be coded separately. |

Microcephaly |
"Head circumference below 2 standard deviations below the mean for age and gender." [PMID:15806441, PMID:19125436, PMID:25465325, PMID:9683597] |
Head circumference is measured from just above the glabella (the most prominent point on the frontal bone above the root of the nose) to the most posterior prominent point of the occipital bone using a tape measure. Some standard charts are organized by centiles, others by standard deviations. It is important to add an indication of how far below the normal standard the head circumference is if an accurate assessment of this can be made. Microcephaly is an absolute term. The term relative microcephaly can be used when the head size centile is less than the centile for height, for example, head size at the 3rd centile with height at the 75% for age and sex. On prenatal ultrasound, microcephaly is diagnosed if the head circumference or the biparietal diameter is more than three standard deviations below the mean. Microcephaly is divided into primary microcephaly, which is present at birth, and secondary microcephaly, which develops postnatally. The crucial difference between these groupings is that primary microcephaly is usually a static developmental anomaly, whereas secondary microcephaly indicates a progressive neurodegenerative condition |

The width of the mouth varies with facial movement and must be assessed when the subject has a relaxed (neutral) face. This term replaces microstomia, small oral aperture, and small mouth because the reduced opening of the mouth is secondary to reduced width. |
